VCP-VVF Practice Test 1 — 30 Questions

Question 1

An enterprise architect is planning a vSphere Foundation 9.0 upgrade and needs to ensure that vCenter Server supports Enhanced Linked Mode (ELM). What is the architectural requirement for ELM across multiple vCenter instances?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

All participating vCenter Server appliances must belong to the same Single Sign-On (SSO) domain during or after deployment.. Enhanced Linked Mode allows administrators to view and manage multiple vCenter servers from a single interface, requiring them to be joined to the same vCenter Single Sign-On (SSO) domain.

Answer

Cross-vCenter Enhanced Linked Mode requires all hosts to run identical CPU models from different vendors.

Answer

The underlying ESXi hosts must be managed by a single master physical blade chassis.

Answer

All vCenter instances must share the exact same external Microsoft SQL database instance.

Question 2

An administrator is reviewing host power management policies in a vSphere Foundation 9.0 cluster. To ensure compliance with strict application performance SLAs while achieving energy efficiency, which DPM (Distributed Power Management) and CPU power management standard should be implemented?

Accepted Answer

Configure ESXi power management policy to 'High Performance' and tune BIOS to OS-controlled or static maximum frequency.. Setting the host BIOS and ESXi power management policy to 'High Performance' or 'Static' prevents CPU P-state/C-state latency overheads that could impact sensitive latency-critical applications.

Answer

Enable aggressive DPM with automated host power-off triggered every 5 minutes.

Answer

Disable Intel SpeedStep or AMD Cool'n'Quiet without specifying an ESXi power policy.

Answer

Set CPU power efficiency policy to maximum energy savings across all database nodes.

Question 3

An enterprise architect is designing a backup and recovery architecture for vSphere Foundation 9.0 virtual machines. Which THREE data transport modes are supported by modern backup software leveraging VADP (vSphere APIs for Data Protection)? (Choose three.)

Question 4

An administrator is designing a vSphere Foundation 9.0 cluster and wishes to implement Network I/O Control (NIOC) version 3 to manage traffic contention on 10GbE/25GbE uplinks. How does NIOC prioritize traffic across system traffic types?

Accepted Answer

By allocating user-defined shares and reservation percentages to specific system traffic types on the distributed switch uplinks.. NIOC version 3 uses shares, reservation, and limits applied to defined system traffic types (such as vMotion, FT, vSAN, iSCSI, NFS, and Management) on the distributed switch.

Answer

By enforcing strict packet drop rules on management traffic when vMotion exceeds 80% utilization.

Answer

By rewriting DSCP bits on physical core switch headers directly.

Answer

By dynamically migrating virtual machines to less congested physical switches using BGP routing.

Question 5

Answer

IPsec transport mode tunnels terminated on the ESXi management vmkernel interface.

Answer

OAuth 2.0 token exchange via the vCenter Lookup Service.

Answer

LDAP over SSL (LDAPS) binding using shared secret service accounts.

Question 10

A security architect is hardening a vSphere Foundation 9.0 environment and needs to restrict access to the ESXi host CIM (Common Information Model) service. Which design practice aligns with modern security hardening standards?

Accepted Answer

Disable the CIM server service on ESXi hosts if hardware monitoring is handled out-of-band via IPMI/iLO/iDRAC.. Disabling unused or insecure management services like CIM (or restricting access) reduces the attack surface of the ESXi hypervisor.

Answer

Grant CIM access permissions to all authenticated Active Directory users.

Answer

Configure the CIM service to use unencrypted HTTP ports for faster hardware polling.

Answer

Route all CIM traffic through the vCenter Server database layer.
